e REFRIGERATOR.

SPECIFICATION formingpart of Letters Patent No. 253,836, dated February 21, 1882. Application tiled January 21, 1881. (No model.) Patentedin Canada April 11, 1877.

- urst, of the county of Gloucester, of the Provrounded by a narrow icereceiving space, a,

ince of New Brunswick, of the Dominion of Canada, have invented a new and useful Improvement in Refrigerators; and I do hereby declare thesame to be described in the'follcw'- ing specification and represented in the accompanying drawings, of which- Figure lis a top view, and Fig. 2 a transverse vertical section, of arefrigerator provided with my invention, such invention being for the purpose of freezing or keeping cool edible animal or vegetable matters for their preservation, it being specially useful for freezing fish and maintaining meats at a temperature such as will prevent theirdecay.

The nature of myinvention is duly set forth in the claims hereinafter made.

In the accompanying drawings, A denotes a case or chamber having what are termed double walls,or a space in each of its sides from top to bottom thereof, filled with a heat non-conductor of some suitable kind.

At or near the middle of the chamber A is an upright and elongated chamber, E, surwhich at top opens out of an ice receptacle or hopper, F, arranged as represented, there being at the bottom of the space c an educt, b, for the discharge of waste water or matters resulting from "the melting of the ice or refrigeratingmixture used in the space c. Besides the said refrigeratin g chamber E, there is in one or each side of it, and between it and the next adjacent side of the case A, a vertical narrow ice-receiver, B, leading outof a hopper, I), arranged in the upper part of the case A. To the mouth of each hopper there is a closing cover, C, and such ice receiver B has. at its lower part an cduct, b,for the discharge from it of Water or Waste matters. There may be in the chamber E shelves or suitable devices for supporting the sh or edible matters to be frozen or kept cool, and there may also be shelves or other suitable devices within the caseA to support meats or articles to be kept cool therein.

In using the refrigerator the hoppersD F and the space c and ice receiver B are to be ber,but that in the case A, which is also still A further lowered in temperature by means of the icereceivers B and D. o o

Experience has demonstrated the valuable advantages of a refrigerator constructed on the plan described, more especially for use on sea-going vessels.

For supporting a iish in the chamber E, I generally employ a tray having a frame to iit to the part of the fish which may be within it. This I use in preference to a fiat shelf, which in consequence of the weightof the iish causes the animal, when frozen, to be liat on its lower side, and thus alters its natural form. It is desirable for several reasons to have the ish in its normal shape as near as possible when frozen. The walls of the chamber E are provided witll internal and external lianges for supporting the shelves c e.

By the construction above described I obtain a refrigerator having compartments of di'erent degrees of coldness, the chamber E, by reason of being surrounded with ice on both sides and top and bottom, being the coldest, while the compartments on each side of the chamber E, not having ice at top and bottom, but only on the sides, are alittle less cold,and the outer chambers, having ice on only one side, do not become so cold as either of the other chambers. This arrangement is advantageous, owing to the fact that different articles of food to be properly preserved require different degrees of temperature, as the 'degree of coldness necessary to preserve some articles would freeze other articles, so as to render them useless.

The ice receivers c B B are each provided at their lower end with -perforations leading to the horizontal channels b b, which are each 2. In a refrigerator, the chamber E and the ice-receiver a, in combination with a hopper, 15 F, having a contracted lower end, whereby an even thickness of ice or freezing-mixture is maintained entirely around the chamber E, substantially as described.
